CALF-WEANING DEVICE.

SPECIFICATION forming part of Letters Patent No. 731,424, dated June 23,1903. Application filed September 20,1901. Serial No. 75,840. (Nomodel.)

To all whom it may concern: I

Be it known that I, ALBERT N. BENDER, a citizen of the United States,anda resident of Milwaukee, in the county of Milwaukee and State ofWisconsin,have invented certain new and useful Improvements inCalf-Weaning Devices; and I do hereby declare that the following is afull, clear, and exact description thereof. I

to My invention relates to devices for preventing calves from sucking atthe udders of their mothers; and it consists in certain peculiarities ofconstruction and combination of parts, as will be fully set forthhereinafter in connection with the accompanying drawings andsubsequently claimed.

In the said drawings, Figure 1 is a plan view of my said device, partlybroken away to better illustrate certain details of construction.

Fig. 2 is an edge View, partly in section, on

the line 2 2 of Fig. 1.

Referring to the drawings, a represents the main portion or shield of mydevice, which is preferably of a generally rounded contour,

with horizontal upper end, centrally cutout,

as indicated at b, and the two parts of the upper edge thus left eachformed with a groove .0 therein, in which grooves are seated two pins cle. The pin d is designed to be permanently secured in place by thescrewf, while the pin 6 is intended to be removable, but held in placeinuse by screw g. A strap h, preferably of metal, surrounds the pin e, theends of this strap lapping the sides of the shield at and being securedthereto, as by rivets it, the said strap being further formed with aslotj therethrough for the passage of the screw g. 'The shield a and thepins d e are preferably of wood, and the metallic strap 40 It serves asan aid in the adjustment and support of the removable pin 6.

In practice the screw 9 is removed and the pin 6 slipped outwardly, andthen the device is applied to a calf, with the pin d thrust into theanimals nostrils on one side up to the cartilage therein, and then thepin e is pushed back in the other nostril to a like distance and securedby the screw g. In this arrangement the shield a will effectually guardagainst the calf sucking, but will not in any way pain or injure theanimal.

As a matter of economy and convenience in manufacture I prefer to makethe device, as herein shown and illustrated, with the two separate pins;but as it is only necessary that one pin or projection should beremovable the projection (I may be formed integrally with the shield, ifdesired in any instance, and the details of construction may beotherwise varied within the scope of my claims without departing fromthe spirit of myinvention.

I'Ieretofore calf-weaning devices have been constructed embodyingsheet-iron frames, some with spike-guarded dishes fitting over the noseof the calf and others with springcontrolled rock-shafts carryingstrands of barbed wire, these'being designed to irritate either the calfor cow, and hence are objectionable from the consequent liability ofinjuring the animals, and such I neither claim nor use. Others havemetallic frames bolted 0r riveted to boards or plates and providedwithspri ug-catches and other operating mechanism; but these variousdevices are all of them heavy and clumsy, and my device is light,simple, and inexpensive, and yet equally efficient as those of thenature described, while free from the objectionable features justenumerated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Acalf-Weaningdevice,comprisingarigid shield having a central openingin the upper edge thereof, said edge being grooved on each side of thesaid opening, in combination with a pair of inwardlyprojecting pinslocated in said grooves, and secured in place by screws, extendingthrough said pins into said shield.

2. Acalf-weaningdevice,comprisingarigid shield having a central openingin the upper edge thereof, in combination with a pair of projectionsextending toward each other across said opening and one of theprojections 5 being removable; a slotted strap around the removableprojection forming a guide therefor in its adjustment, and having armssecured to the shield, and a securing-screw passed through thestrap-slot and removable projection into the said shield.

3. A calf-weaning device,comprising a rigid IOO shield of uniformthickness throughout, and i through said pins andinto said shieldthrough having a central opening in the upper edge the bottom Walls ofsaid grooves. thereof, said upper edge, on each side of said Intestimony that I claim the foregoing I opening, having an opensemicircular groove have hereunto set my hand, at Milwaukee, in
